To all whom "it may concern Be it-known that I, HORACE WVYMAN, a citizen of the United States, residing at \Vorcesteryinthe county of lVorcester and State of Massachusetts-have invented a new and useful 3 Pattern-Card-Repeating, Ma- .chine, of whichlthe following is a specification. Y 1

This invention. relates to a machine for duplicating =or repeating the pattern cards used inlarge numbers in the operation of Jacquard and certain 'other types of looms.

A machineof this general type is shown in the patent: to' Boyle No. 304 864; issued September 9, 1884:. 'For' the operation of {such machines a-se't of original pattern cards must first be providech whichare used'in the machine as master cardsfrom. which any desired number (if duplicate sets may bereproduced. y

My invention relates vparticularly to improved devices for selectively. determining the punches to be rendered operative and to improved constructions in the punches themselves,

It is the principal object of my invention to provide aconstruction. by which a single (vices may be utilized to produce either posi-' tive or negative pattern cards from a single set of master cards.

- i The terms .positive?andv lnegative? have s a fwell understood meaning. in this art and indicate respectively'that the positive (card is an exact reproduction of the master card and that the negativecard' hasYits perforated" and unperforated portions interchanged and reversed relative-to the master card.

A still: I to :prov de an improved{construction in the punches which perforate, the duplicate cards.

With these and other objects in- 'VllQW my invention, consists of certain :de'vices, ar

rangenients and combinations of partsvhich will be hereinafter described and more particularly pointed out in the ap pended claims.

A preferred form of my I invention shown in the drawings in which,

Fi 5 is an enlar ed sideelevation similar 2: I a: v m to. Fig. 2 but showing-the devlces for producing negative duplicates 'ofthe master card, and Fig ti is a partial face view of a ofthe master cardshown negative duplicate in Fig. 3. I

I11.-Fig. 1 I have shown a single transverse set of punches 10 such as would beutilized to produce a single vertical row of the perforations. shown in the, duplicate cards in Figs." 4 and-.6. These punches are freely movable verticallyin a fixed guide: *plate 11. The punches 10 are all of sub stantial-ly the same length and are provided withshoulders ll 'upon their upper ends which limit the downward: n'iovement of the punches.

Positioned above eachpunch is an'intermediate bar 13, these bars being of different lengths (as clearly shown .in Fig. l) and having their upper ends positioned adjacent a series of sliding keys 1%. The bars 13 are in-close sliding contact with each other and completely fill a rectangular space inclosed by the lower portion of a fined frame member 18, side walls (not shown)- integral'with or carried by said frame member and aretaining bar, or plate (not shown) detachably secured to the front edges of the side walls;

When certain of these keys 151: are, projected -to the right in l, as indicatedat 14,

." punches10' are restrained I from fupp'ard movement, but when the keys are withdrawn,

and punch 1e 'orresponding intermediate bar- 113- and sliding key, this spring being conveniently By the provision of'the intermediate bars 13, I am enabled to use a single size andbe readily removed and replaced in the guide plate 11.

The blank cards B guide by an'intermittently actuated feeding cylinder 16. The card guide 15 is mounted upon vertically movable plungers Lia Ifix'ed perforated frame member 24. head upon the pin engages the frame mem- 17 which may be intermittently actuated by any suitable mechanism.

The devices for vertically moving the card guide 15 and for intermittently feeding the cylinder 16 constitute no part of my invention and may be of the type shown in the Royle patent or of any other desired type. The sliding keys 14 are supported in a fixed frame member IS'and areeach connected at their rear ends with rods 19 having their opposite ends supported for slid- -ing movement in a fixed frame member 20.

A light coil spring 21 is provided for each positioned between theframe member 18 and a collar 22 upon the key.

Each rod 19 at its rear end engages a short headed pin 190 mounted in a second The ber 24 and limits rearward movement of the rod 19 and attached key 11 under the influ ence of the spring 21.

Each rod 19 and its corresponding pin 190 operate together as a single element and might be formed integrally except for certain difficulties in manufacture and assem-- rods 19 and keys 1 1, I provide interchangeable sliding carriers 40 and which are mounted to slide horizontally upon ways 30. For actuating the carriers 1. provide a bell v crank 31 movable about a fixed pivot 32 and connected by a rod 33 to suitable actuating mechanism (notlshown). The vertical arm of the bell crank 31 is adapted to be connected by a link 41 to the carrier 40 or by a link 51 to the carrier 50. The devices for actuating the rod 33 and the feeding cylinders 25 and 26 form no part of my invention and may be of any suitable or desired type.

-The parts thus far described, With the exception of the carriers 10 and 50 and the links 41 and 51, are all utilized in the opera removing the front re-= from which the duplicates are produced are drawn through a card tion of the machine, whether positive or negative duplicates are to be produced. I will now describe the carrier 4-0 and the parts associated therewith which are adapted to the production of positive duplicates.

. The carrier -10 is provided with a hollow rectangular casting 12 secured to the carrier 10 by any suitable means such as the screws 43 and having a plurality of auxiliary plungers 4A: freely slidable horizontally in said casing. 'Each' plunger is provided with a coil spring 45 encircling the plunger and engaging a collar =16 upon, the plunger to force the plunger to the right as viewed in Fig. This movement to the right is limited by .the engagement of the collar 46 with the side wall of the casing 42. the normal position of the plungers being that of the plunger 1.4 in Fig. 2. A card guide 47 is fixed to the frame member :B-l and comprises two parallel perforated plate; through which the auxiliary plungers 11 are freely movable. In the actual operation of thedevice, a master card A is positioned within the card guide 17 and an index pin 48 (Fig. 3) 1s pro ected through an enlarged perforation in the master card to accurately register it in the card guide. The carrier 40 is then moved to the right and those plungersdi (Fig. 2) which are alined with the perforations in the master card pass freely through said perforations and engage the ends of the correspondingpins 190. As the springs -15 are of greater strength than the springs 21, the plungers 41 move the corresponding pins 190 and rods 19 to the right and slide the keys connected therewith into position to restrain upward movement of: the corresponding punches 10. The plungers 11 which are alined with unperforated portions of the masteigcard slide rearwardly relatively to the-casing and the corresponding rods 19 are undisturbed. It, will thus appear that the punches corresponding to the perforations in the master card A are alone rendered operative and that the perforations in the duplicate card B (Fig. 4) will be identical with those in the master card.

Referring to Figs. 5 and 6, the special devices for producing negative cards will now be described. This mechanism is much simpler than the mechanism for producing positive cards and comprises simply a \Ql" tical card guide 52 mounted upon the carried 50 and having front and rear perforated plates through which the projecting ends of the pins 190 are freely movable. In the operation of this device, the card is positioned vertically as previouslydescribed and contering devices (not shown) may be provided for accurately registering the card.- The card guide and card, supported on the carrier 50 are thereafter moved to the right (Fig. 5) and the unperforated portions of thejcard engage the ends of the pins 190 vcorresponding to certain rods 19, moving them to the right to the, position indicated at 19* in Fig. 5. Such movement projects the corresponding. keys 14 and prevents vertical movement of the corresponding punches 10. At the same time the perforations in the mastercard pass freely over the remaining pins 190 and the keys associated iftherewith remain in inoperative position.

It. will thus be seen that a blank 'spaceupon the master. cardfproduces aperforation in the negat ve card, while a perforation in'the I master card leaves a blank space in the nega- 5, tive card. The resulting card is thus a negafica'tions can be made therein by thoseskilled in the art without departing from the spirit and scope thereof as set forth in the claims andI do'not wish to be otherwise limited to the details herein disclosed. but-- XVhat I do'claim is 1.
